The Quantum Resistant Ledger (QRL) is a 'fully quantum resistant blockchain network, using PQ-CRYPTO recommended/IETF standardized cryptography'. The QRL utilizes a hash-based eXtended Merkle Tree Signature Scheme (XMSS) instead of ECDSA, which is reportedly vulnerable to quantum attacks and found in many other blockchain projects. The project claims that the security of its platform is complemented by a suite of applications and a development ecosystem which allows users to 'easily build blockchain applications on its provably quantum resistant network'.

Solve.Care is a healthcare platform company that uses blockchain to redefine care coordination, improve access to care, reduce benefit administration costs, and help reduce fraud and waste in healthcare around the world.

The Solve.Care platform (Care.Platform) allows for digital health networks, called Care.Networks, to be built and run for patient-centric care that can be based on medical conditions, economic and social needs, creating an entire healthcare ecosystem. Using Care.Platform, clients can launch networked, interoperable healthcare dApps, within a very short time frame.

Care.Networks on Care.Platform use the SOLVE token, a utility token that is used for inter/intra network payments and transaction fees. It also has additional uses including developer rights, staking, marketplace payments, and platform access fees.

Peercoin, also known as PPC or Peer-to-Peer Coin, was created by Sunny King and his team and launched in August 2012. It is the first blockchain to implement Proof-of-Stake consensus.

The primary inspiration behind the creation of Peercoin was to address a number of perceived shortcomings of Bitcoin, including energy efficiency, security and sustainability, decentralization and long-term viability.

Essentially it was designed as an enhanced replacement for Bitcoin. As such, it was originally forked from Bitcoin and uses the same UTXO style blockchain. However, Peercoin's code was modified to introduce Proof-of-Stake as its primary consensus protocol. The next section explains how this makes for a better blockchain.

Given that Peercoin uses most of the same code, it can easily port new features from Bitcoin and utilize any of the supporting infrastructure, including tech advancements like Taproot or Lightning Network. Peercoin is the only Proof-of-Stake blockchain that uses modern Bitcoin code, making it the perfect drop-in replacement.

Peercoin also has a dedicated community, is actively developed, fairly distributed, has low barriers of participation, can do everything that Bitcoin does, minus the 13 TWh of energy usage, and it's not a scam.

Aergo describes itself as an open-source enterprise blockchain platform optimized for hybrid deployments, which consist of both permissioned and permissionless blockchain architectures. It includes support for SQL allowing for easy data handling and familiar smart contract programming for developers.

The platform is built and utilized by Blocko, the Samsung-backed South Korean blockchain technology company that, according to Korean media sources, has deployed production blockchain solutions for large-scale clients including Lotte Card, Shinhan Bank, Korea Exchange, Hyundai Motors, and more.

Library Credit (LBRY) is a platform that seeks to simplify the way digital content is distributed and accessed by both consumers and producers.

Library Credit uses a decentralized model to be fair, free, and open to all the involved parties.

More specifically, the platform functions as a distributed network built on top of a protocol that makes it easy for publishers to charge a fee to content consumers without censorship or the need for a middleman.

The project was launched towards the end of 2018 and is now serving an active community.

Kleros (PNK) is a decentralized dispute resolution project that launched in July 2018. It is an open-source online dispute resolution protocol that uses blockchain and crowdsourcing to adjudicate disputes fairly.

Kleros offers a middleman service for decentralized applications (DApps) and their users. If the service provided by the application does not create a dispute, Kleros acts as a trustless third-party service for payment.

When a dispute does occur, however, each party can apply for arbitration through the Kleros arbitrators that are selected from the owners of PNK tokens. PNK is an Ethereum-based ERC-20 utility token with a fixed supply.

At this point, the jurors can make a decision that will favor either party. The arbitration fees are distributed to all arbitrators in the form of ETH; jurors who have issued a minority decision lose part of their PNK tokens for the benefit of the majority of jurors. This decision can be appealed, at a cost. The stated mission of Kleros is to offer easier access to justice and improve individual freedom.

Kleros charges a cost that is payable in ETH and is provided by the parties to the dispute or drawn from the funds previously locked in escrow.
